At the same time, the winding motor 121 is driven to reciprocate in the direction of the central axis of rotation by the servo motor 119, and the carrier tape C spirals to the bobbin reel B. Rolled up into a shape. That is, the rotation of the bobbin reel B is detected by the encoder, the rotation speed of the servo motor 119 and the switching timing of the forward / reverse rotation are controlled based on the output of the encoder, and the carrier tape C is wound around the bobbin reel B at a predetermined pitch. take. For this reason, the winding length of the carrier tape C wound around the bobbin reel B can be increased. Moreover, since the maximum value of the transmission torque of the winding motor 121 is regulated by the powder clutch 122, the tension at the time of winding the carrier tape C does not become excessive and can be wound with an appropriate tension.

  Further, during winding of the carrier tape C onto the bobbin reel B, the slider 181 moves to the take-out position immediately below the bobbin reel B, and swings in the direction in which the link member 185 of the slider 181 separates, so that the receiving bar 187 is moved to the bobbin reel. The slider 192 waits in advance to receive the reel B, and the slider 192 lowers the insertion cylinder 195 to a predetermined position by the lift cylinder 194 at the transfer position in advance. When the winding of the carrier tape C onto the bobbin reel B is completed and the carrier tape C is cut by the cutting mechanism 20, the movable support member 113 moves away from the fixed support member 112 and the plunger 124 is moved. Protrudes and the bobbin reel B, which has been wound up, falls onto the receiving bar 187.

  Thereafter, the slider 181 is placed on the receiving bar 187 on the bobbin reel B and moves toward the transfer position. When the slider 181 reaches the transfer position, the lifting rod 196 is inserted into the bobbin reel B by the insertion cylinder 195. Inserting into the hole, the lifting cylinder 194 operates to lift the bobbin reel B. Then, the moving cylinder 193 is actuated to convey the slider 192 to the payout location and pay out the bobbin reel B. Thereafter, the slider 192 moves to the transfer position and prepares for the next.

  Further, almost simultaneously with the movement of the slider 181 toward the transfer position, the swing arm 156 swings to the delivery position and lifts the empty bobbin reel B between the reel side plates 114 and 115. Then, the movable support member 113 is driven to the fixed support member 112 side, and the bobbin reel B is sandwiched between the reel side plates 114 and 115. Thereafter, similarly, the cut end of the carrier tape C is fastened to the core surface of the bobbin reel B, and the bobbin reel B is rotated and reciprocated within a predetermined range in the direction of the central axis of rotation. C is wound up, and this is repeated thereafter. Therefore, the carrier tape C can be efficiently wound around the bobbin reel B without any manual work by the operator.

  As described above, the tape take-up device according to the first aspect of the invention is configured such that an empty bobbin reel is placed on the stock rail by the bobbin reel replenishment mechanism, and the tape is taken up on the bobbin reel of the take-up unit. When the bobbin reel is not allowed to roll by protruding a stopper member on the stock rail, and the bobbin reel that has finished winding the tape is taken out from the take-up portion and is in the take-out position. The stopper member is immersed and the bobbin reel rolls on the stock rail by its own weight toward the end on the take-up part side, and the empty bobbin reel reaching the end of the stock rail is lifted by the lifter to take up the take-up part Attach to. For this reason, the empty bobbin reel can be automatically mounted on the winding unit by a simple mechanism, the winding device can be achieved at a low cost, and the number of man-hours can be reduced.

  Then, the slider is positioned below the take-up portion, and the support rod is tilted in the approaching direction (vertical upright direction), and waits in this state. Then, when taking out the bobbin reel that has been wound up from the take-out position, after the bobbin reel that has been taken up by the take-up portion is received on the receiving rod by the take-out mechanism, the slider is moved to the pay-out portion, The payout unit pays out to the mounting table by the transfer mechanism. For this reason, the bobbin reel which has completed winding of the tape can be automatically carried out with a simple mechanism, and the number of man-hours can be reduced.

In the tape take-up device according to the second aspect of the present invention, a powder clutch for adjusting the transmission torque of the take-up motor is interposed in the power transmission system of the bobbin reel, and is transmitted to the take-up motor. The maximum value of torque is regulated. For this reason, the tape can be wound around the bobbin reel with an appropriate tension.
According to a third aspect of the present invention, there is provided a tape take-up device for reciprocally driving a range corresponding to the tape take-up width of the bobbin reel in the direction of the rotation center axis of the bobbin reel by a spiral winding servo motor. Can be wound around a bobbin reel in a spiral shape (spiral shape), and the winding length of the tape around one bobbin reel can be increased.
